A total of 180 brown eggs were obtained from one 27-week-old flock of Hy-line brown-laying hens raised in a cage system. Correlations were evaluated using Pearson's correlation coefficient (r). The results showed strong correlations between Haugh unit and albumen height, eggshell color CIE L * and reflectivity, egg weight and width, egg weight and length, eggshell color CIE L * and CIE a * , eggshell color CIE a * and reflectivity, and shape index and egg length ( P <0.001).

In cell culture, it is well known that the culture medium has a significant influence on cell growth and maintenance of cell characteristics. This study aimed to adjust the culture medium to make it more suitable for QM7 muscle cells. A culture medium was prepared by adding 2% chicken serum (CS) instead of 10% tryptose phosphate broth (TPB) to the conventional culture medium. In the culture medium prepared with CS, the QM7 muscle cells changed from a pointed, thin to a broader shape. In addition, they grew and divided more rapidly in the new culture medium than in the conventional culture medium. The number of cells increased faster in the CS-containing culture medium from day two after passaging, and significantly increased from day three. The muscle cells grown in the medium containing CS maintained their undifferentiated state prior to differentiation. Myotubes formed well when the cells were maintained in CS-containing medium, resulting in a longer length and uniformity. According to the above results, it is clear that the culture of QM7 myocytes using a medium containing CS rather than TPB helps obtain better results in cell maintenance and differentiation.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89486348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 200 one-day-old broilers (Ross 308) were allotted to one of four treatment groups in a randomized complete block design in five replicates with 10 birds per pen during a 5-week growth experimental period. Birds were fed a corn-soybean meal-based diet with or without the addition of 0.025, 0.050, or 0.075% exogenous hydrophilic emulsifiers. The diets contained 3,025 and 3,075 metabolizable energy/kg for Phases 1 and 2, respectively. For each phase and the overall experimental period, body weight gain (linear, P <0.05) and feed conversion ratio (linear, P <0.05) improved in proportion to the dietary exogenous hydrophilic emulsifier level, while the average daily feed intake was not affected by dietary treatment. Improvement in growth performance by dietary treatments was observed during the last two weeks rather than the first three weeks of the growth phase. In carcass traits, abdominal fat content increased as dietary exogenous hydrophilic emulsifier level increased (linear, P <0.05), whereas dietary emulsifier level did not affect the relative weight of the liver, breast, and leg muscles. In conclusion, addition of dietary exogenous hydrophilic emulsifiers from 0 to 0.075% in broiler diets improved the growth rate and feed efficiency of broilers without any deleterious effects on nutrient digestibility, although a corn-soybean meal-based diet had less energy content (3,025 and 3,075 metabolizable energy/kg) for 0-3 weeks and 3-5 weeks, respectively.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78869276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various ALV viral subgroups exist, with infections occurring via specific host receptors. The susceptibility or resistance of avian species to the ALV-A and K subgroups is determined by the host receptor, the tumor virus locus A ( tva ) gene, while that to ALV-B depends on another host receptor, the tumor virus locus B ( tvb ) gene. The resistance alleles of tva and tvb have primarily been identified in China, but none have been detected in Korea. We analyzed the frequencies of tva and tvb genotypes in White Leghorn (WL), Korean Ogye (KO), and Korean native chicken (KNC) breeds, and assessed the resistance to ALV subgroups. In WL, both tva and tvb had various genotypes, including susceptibility and resistance alleles, whereas in KO, tva and tvb resistance alleles were dominant. In KNC, tva susceptibility and resistance alleles were mixed, whereas tvb resistance alleles were dominant. In addition, we showed that there were differences in the splicing pattern of tva transcripts and the expression level of tvb transcripts within breeds. Finally, we confirmed that ALV resistance depended on KO and KNC genotypes by in vitro infection of chicken embryonic fibroblasts with ALV. These results highlight that some KO and KNC individuals are naturally resistant to ALV subgroups A, B, and K, and will facilitate the preservation of economically superior traits through selective breeding.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91212704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the growth performance, vitality, and stress response of 479 male and 608 female chickens from 1 d to 12 weeks of age. The body weight, feed consumption and feed conversion ratio were measured as growth performance. The survival rate, amount of telomeric DNA, DNA damage rate, heterophil-lymphocyte ratio (H/L ratio), and heat shock protein (HSP)-70, HSP-90α, and HSP-90β gene expression levels were analyzed as indicators of vitality and stress response. Body weight was significantly higher in male chickens than in female chickens after 2 weeks of age (P<0.01). Feed intake was higher in male chickens than in female chickens, whereas the feed conversion ratio showed the opposite trend. The survival rate was significantly higher in female chickens than in male chickens (82.8% vs. 73.8%, P<0.05). Stress response analysis revealed no differences between male and female chickens in terms of telomeric DNA content, DNA damage rate, H/L ratio, and HSP gene expression levels. Taken together, it was concluded that there was a significant difference in the growth performance and survival rate between male and female Korean native commercial chickens, whereas there was no difference in the degree of stress response between them. Therefore, in terms of the productivity of Korean native commercial chickens, it is judged that separate-sex rearing is much more advantageous than mixed rearing, regardless of the physiological characteristics of males and females.

Thirty-six 40-wk old Lohmann Brown hens were randomly assigned to three groups based on body weight, with four cages with three layers each. Laying hens were divided into one of the following groups: control (CON), powdered CoQ10 (PCoQ, 100 mg/kg diet), and emulsified CoQ10 (ECoQ, 100 mg/kg diet).

However, there was no significant difference in blood TAP levels between the PCoQ and ECoQ groups, although a decreasing trend (P<0.13) was observed for levels of TAP in the ECoQ group. The mRNA expression and specific activities of superoxide dismutase, glutathione peroxidase, and catalase in the liver were not affected by dietary CoQ10 or type of CoQ10. However, hepatic lipid peroxidation in the ECoQ group was lower ( P<0.05 ) than in the CON group. In conclusion, emulsified CoQ10 increased blood TAP and decreased hepatic lipid peroxidation without affecting antioxidant enzymes, suggesting that emulsified CoQ10 might be more applicable as an active antioxidant supplement than powdered type in laying hens.","PeriodicalId":17845,"journal":{"name":"Korean Journal of Poultry Science","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81664348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
